Re: Hp8558b spectral analyzer (2/2)
The capacitor in the original input assembly will block DC from reaching the attenuator. Yours may have been damaged by having DC or excessive RF level applied to the input. The attenuator should

Hello Dave, Thank you for your answer. I've this manual but (unfortunately) the information about phase slope and reflection group delay are not included and the drawings contain no tolerances. In

Re: Capturing screenshots on 8934C
Hi, For the 8924C, you must have a special cable to use it with the BTS software. Have you this cable? Wiring is OK? Printer config set to DESKJET BTS software and cable to have for 8924C

It just means that you need to change the switch position and change the fuse itself, NOT the fuseholder. Richard ________________________________ Sent: Wednesday, June 9, 2021 2:12 PM To:

Re: HP 3457A mains voltage setting
Crap... does that mean I need a different fuse holder before I can start using this? The unit came from the US and I am in Europe.

Re: Hp8558b spectral analyzer (2/2)
Hello, NJ902, please Can you be more specific What¡¯s a DC block? For me a capacitor dont't indicate 0 ohm? What is excatly the impedance of the attenuator? *If someone have a HP8558B analyzer and

Re: Hp8558b spectral analyzer (2/2)
The purpose of the capacitor in the input assembly would be a DC block. It appears that the input assembly was changed on your unit. The attenuator input section appears to be damaged,

Verifying HP905A Sliding Load - request for further technical specs
Dear all, I would verify some of our 'old' calibration equipment and my question is: Does anybody have the spec sheet from the HP905A sliding load (1.8-18GHz)? I'm interested in the following data: -

Re: HP 3457A mains voltage setting
Looking at a picture of 3457A, circular one is the fuse holder. The picture I found says 80mA for 220/240 and 200mA for 100/120mA next to it, in consistent with the message from "tmillermdems". Ozan

Re: HP 3457A mains voltage setting
Not certain about the settings (shouldn't it be in the manual?) but the fuse is generally 1/2 the 120 volt rating, and should be listed on the back.? I know that Tek generally has a "gross" setting,

Running the Agilent vintage PDNs below 300KHz
I am curious what limits the E835xA PDNs to 300KHz and if there is a way to override it, with the understanding that the performance would be reduced?

Paul, thank's for your answer. That¡¯s the problem, I¡¯ve never been able to display a signal with the RF plug. In fact, my first question was whether this catch was smeared because you can¡¯t see

HP 3457A mains voltage setting
Hi all, I've noticed that my 3457A has two settings for the mains voltage. One is a circular selector with a flat head screwdriver slot, the other is a pair of sliders. I need to change it from US to

Re: Hp8558b spectral analyzer (2/2)
Hi From the video it appears you are not putting the test signal into the RF input why ?? Also best advice is to get a few adapters and leads rather than putting signals in with a bit of wire Regards

Re: Capturing screenshots on 8934C
I have the BTS laptop utility. It works perfectly on my 8935, but I can't get it to work on the 8924. I use the 8924 more because of it's auto-ranging feature.

Good advice Bruce, this is my initial findings, I will study more carefully.

Re: 8566B 1dB scale trace not linear at bottom of screen
I remember there being a variable resistor with fixed resistors that needed to be changed only if the variable did not provide enough range. Think I'd read a bit more B4 proceeding. Cheers! Bruce
